idea after all.
Fix cross-builds and ia64 builds. gnu/lib/csu/Makefile is modified to
pre-include osreldate.h and gnu/usr.bin/cc/cc_tools/auto-host.h
will avoid including sys/param.h if __FreeBSD_version is already defined.
non-PIC libgcc.a. Linking non-pic code into a shared library is not
a good thing. It happens to break amd64 at compile time, and the ppc
folks want it too. The problem is mainly with C++ code, unwind-dw2.c
in particular. Most of the other functions in libgcc.a are self
contained so most of the time it isn't a problem. The dwarf2 unwinder
is not safe though since it does make global variable references.

give the cvs tree a surviving a 'make world'. One of the two diff chunks
is already in gcc-3.3, the other has been committed to gcc's HEAD and
is in the pipeline for gcc-3.3.1 (but has not been committed yet).
The first chunk simplifies an excessively complex assembler statement
when generating switch jump tables. The use of '.' causes as(1) to choke
on big files. Use a simpler form instead. This is only an issue for
TARGET_64BIT mode.
The second chunk fixes an internal compiler error when compiling
libc/stdio/vfprinf.c. While this is supposedly only an issue for
64 bit mode, it does touch the 32 bit i386 code paths, so this patch
is only applied for TARGET_ARCH == amd64 to keep the risks down.
Breaking gcc at the 11th hour would suck.
This will be removed when it is time to import gcc-3.3.

under way to move the remnants of the a.out toolchain to ports. As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL. It has already lasted WAY beyond
that.
Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

cc1plus can apparently be built if you happen to have
/usr/bin/gperf, or set CXX to point to a C++ compiler
that can build gperf(1) in the bootstrap-tools stage
of buildworld.
The problem is the GCC driver now turns STANDARD_EXEC_PREFIX into a relative
path -- "<basename argv[0]>/../../libexec" for our normal install location.
However, in the middle of `buildworld' we need
"<basename argv[0]>/../../../../libexec" due to the prefix we tell the GCC
driver. But either the GCC driver is buggy, or we are confusing it, as it
tries to exec "<basename argv[0]>/../../libexec/cpp0" as if it were installed
in the normal place (but isn't).
MD_EXEC_PREFIX is still absolute, so I'll use that for now. I would like to
later make it so MD_EXEC_PREFIX is set only for `buildworld', as
MD_EXEC_PREFIX is also in the search path for libraries. Don't ask me why!
Another way is to add ${OBJFORMAT_PATH} (as set in CROSSENV) to the PATH
in src/Makefile.inc's WMAKEENV.
bits. Also remove comment about keeping in sync with other instances in
the source tree -- it was too easy to get out of sync, so the other
instances now use this instance.
collect2 was added based on the need of -frepo. However, -frepo is currently
broken on -CURRENT (Gcc 2.95.4 20020320 [FreeBSD] / ld 2.12.0 [FreeBSD]
2002-04-10). It is also broken on RELENG_4 (Gcc 2.95.3 20010315 / ld
2.11.2 20010719), so there is no need to MFC collect2 there yet. I have
a feeling the brokeness is due to the wide difference between the libiberty
bits of Gcc 2.95 and the later ld.

about 'STANDARD_EXEC_PREFIX'. It is used now and is needed if one does not
set 'MD_EXEC_PREFIX'.
Do not define a 'MD_EXEC_PREFIX'. It is not needed, not used in the
cross case, and just ends up causing "/usr/libexec" being added to the
library search path.

I am committing this here rather than in gcc/config/freebsd.h because the
profiled libgcc only exists with the native system compiler. It is not
created by a stock FSF build and we will never be able to get these bits
committed to the FSF CVS repo. Thus this is very much a FreeBSD "native"

It is here in case we decide we want the directory to match the binary name
since neither the binary nor the source file(s) are named 'cccp' any longer.
Really irritating changes are the "forced" layering of malloc + friends
in order to use the GNU versions. Sorry, we have a *very* fine malloc,
and we will use it. Period. Even more irritating is that the GNU people
now want to replace ctype also!! So we partially dike it out here.
We now have to use the GCC stdarg.h varargs.h. We simply have no choice
as it has an internal representation that we really cannot properly define
in our headers.
This thing grew. We now have to link with many more files as if it
were one of the driver programs. We also have to deal with the very
irritating layering of malloc and friends. Our malloc works *very*
well thank you. Thus we will use it.
"build-tools". If we do not do this, the "depend" stage of
"buildworld" will build ``.depend'' and it will record the wrong
library and header dependencies (DESTDIR=${WORLDTMP}). Even worse,
the "all" stage may clobber build-architecture-format build tools
built in the "build-tools" stage with target-architecture-format ones.

This is wrong. The library should only be linked in if it contains
non-common, non-weak symbols which are needed by previously linked in
objects.

build-tools target and by the actual target. In a cross-building situation
proj.o is both a native object and a cross-object (i.e., for the target
arch) and thus doesn't work. Creating seperate opjects from the same
source file solves this...

This seems caused by wrong dependency information. Dependency
information shouldn't be created for build-tools sources.
